							<h1 class="title-power" >Power system</h1>
						  <p class="ptext" >With no doubt power plays a huge role in all audio systems. Most portable designs suffer from universal power designs that highly compromises signal processing quality. DTR1 adapts a dual high-density battery customized power system, designed for High-Fidelity while ensuring separation of digital and analog power to eliminate circuit noise from the source, alike an enhanced DAP + Amplifier system but with a minimal path and hard soldered joints with no compromises. The &plusmn;8.5V PSU remarkably improves efficiency of clean power supplied to the system, with noticeable qualities in transparency and background noise control without the need to excessively damping the output.</p>

						  <p class="ptext" >DTR1 selects AK4490EQ for its reliability and specific sound performance, the chipset supports up to 32Bit/768K and switchable digital filters offering different auditory experience. AKM, since its first delta-sigma D/A converter (DAC) in 1989, strives for reproduction of the original sound. Such becomes the philosophy ''Velvet Sound'' aiming at providing an active space in the reproduction of sound just like a live performance.</p>

						  <p class="ptext" >In pursuit of "Real Live Sound", an important part along the signal path - LPF (Low pass filter) adopts two TI OPA1611 on each channel (L/R). Together with the AK4490 chipset the design illustrates a very lively, dynamic output. The amplification circuitry features a mature AD8397 implementation with low distortion, super loading capability not to mention slew rate of 53v/us and 69M bandwidth, further boosted with &plusmn;7V power supply. The ideal power supply breaks limitations in shaping sound, achieving powerful, clean sound with effortless extension.</p>
